Mt. Sentinel – Running Up For Air

Description:

Complete as many laps on Mt. Sentinel as possible! Whether it’s one lap or a dozen, test yourself and have a blast on Missoula’s favorite mountain and most popular trail while taking a stand in the fight for improved air quality.
The race begins at the M-Trail parking lot and climbs the switchbacks to the M. The route then climbed the steep Northwest Ridge Trail to the Sentinel summits (note: this is a change from 2020, when the course was an out/back up the M Trail and Boy Scout Trail). A small aid station awaits on top. Head over the summit and descend back down to the base area on the Boy Scout Trail, then the M Trail. While only 4 miles long, each lap on this classic route has ~1,900’ of elevation gain. Repeat this route as many times as possible or until you Refuse To Continue (RTC). The time of year (February!) is intentional as it coincides with reduced winter air pollution but is safely before the summer fire season.
